UDP Port Testing

Does anyone know of a plugin (or a way) to test a UDP port?  Yes, I know
that may sound strange (IE UDP IS stateless) but I need to be able to
basically test if a port responds or not. 
Or failing that.  I seem to remember a long time ago a plugin for BB
that used the qstat game server query program to test game servers. Does that ring a bell to anyone?
